Patented Dec. 23, 1941 UNITED: STATES PATENT OFFIQE AIR-CONDITIONING. APPARATUS RADIATOR Philip v. Dj..Neff, Tucson, Ariz. Appncationnp irn; 1940, SerialNo. cam-4a Claims.

My invention relates to an air-conditioning apparatus and has for its principalobiects to generally improve upon and simplify the construction of the existing forms of air-conditioning apparatus and particularly the cellular structure of the radiators thereof, further, to providean improved form of radiator comprising a plu rality of cores shaped and arranged to form adjacent air ducts and water circulation spaces, the same being arranged so as to effect exchange of temperatures within confined limits and further, to provide an air-conditioning radiator structure that may be economically produced, capable of being readily assembled or taken apart in order to facilitate the periodic cleaning of the parts of the radiator.

With the foregoing and other objects in view, my invention consists in certain novelfeatures of construction and arrangement of parts that will be hereinafter more fully described andclaimed and illustrated in theaccompanying drawing in which:

Fig. 1 is a perspective view of an air-conditioning radiator constructed in accordance with my invention.

Fig. 2 is an enlarged cross section taken on the line 2-2 of Fig. 1.

Fig. 3 is an enlarged vertical section taken onthe line 3-3 of Fig. 3.

Fig. 4 is a horizontal section taken on the line of the air-conditioning apparatus with which my improved radiator is associated.

Referring by numerals to the accompanying drawing and particularly to Fig. 5 which illustrates diagrammatically anair-conditioning apparatus of the type that may be usedfor cooling and conditioning air in residences, offices, store rooms, and the like, If! designates a housing that contains a conventional cooling rack which may be formed of woodor metal, II the drip pan that is disposed on top of the cooling rack contained within the housing l0, I2 the sectional radiator forming the subject matter of my invention, l3 the motor driven fan that forces air through a flue M to the cooling rack contained within housing l0 and which fan also forces air through a flue IE to the radiator, IS a tank that receives the water after it passes through the cooling rack and IT a pump that forces the cooled water from tank [6 through a conduit. l8 that delivers said cooled water to the top of the radiator.

The radiator contemplated by my invention and a preferred form of which is iilustrated ln cross section-in-Figs. 22nd 3 comprises a plurality of shallowpans l9 suitably supported spaced; relation, one above the other, and arranged between said pans are parallel air ducts that are formed by a plurality "orspaceuz fins or thin sheet metal, preferably copper.

In the lowermost one of thepans 19' illustrated in- Fig. 2, the lower portions of sheets of thin metal are bent and assembled soas to form. a: plurality ofnarrow v -sha'ped ai r ducts or con duits 20 that. extend lengthwise of the pan- Hiand the upper portions of the-- sheets of metal used in forming these ducts are extended upwardly' in parallel spaced relation to form a plurality' of longitudinally disposed fins 2!. These fins extend ashort distance above thetop of pan I 9 and supported on-theupper' edges of said: fins 21 are-the lower endsof similar'fins 2?. that form a part ofthe radiator core that is disposed abovethe core associated with the pan I 9;

Fins-22 are formed from thin-sheet metal and those portions of the metal above said fins are shaped so as to form substantially w-s apec water flow ducts or conduits 23; the upper ends thereof communicating with the lower portion 0f the water chamber within the pan- I9 that is above that pan containing the air ducts 28.

Asillustrated in Fig. 2, the sheet metal utilized in forming the fins- 2-2 and the-inclined walls to the sides of'the water ducts- 23 may heconstructed so as to form thebottom of the upper one of the pans l9. a

Asa result of the construction just described, open-ended air ducts 24 are provided, which. extend the entire lenth of the pans l9 betweenthe fins 21 and 22' and larger air'du'cts 25 are formed between the pairs of fins 2 land 22 and between the water spaces 23 and the inverted V-"shaped water spaces 26 that are formed betwe'enlthei V:-'

Where theradiator is constructed a series of superimposed cores, the uppermost pan of each core receives the lowermost portion of the cellular structure of the core above which comprises the thin sheet metal plates that are shaped to produce the V-shaped air ducts 2|] and fins 2| (see Fig.

Cool water from tank It is driven by pump ll upwardly through conduit I8 and discharges through suitably located outlets into the pans l9 and after filling and flowing through said pans and through the water ducts 26 and 23, said water discharges from the opposite end of the pans through suitably located outlets 21.

Alr'ls driven by fan I3 through duct 14 into the cooling rack within the housing H) and simultaneously air is driven by the fan through duct [5 into and through the air ducts 29, 24, and 25. The ends of the pans l9 are closed by end walls la and the end portions of the air ducts 20 which extend downwardly into the pans 19 are closed. The ends of the air c ircula tiorrducts 28,

24, and 25 are open.

Inasmuch as the fins 2| and 22 to the sides of the air ducts 24 are continuations of the thin sheet metal walls that form the water fiow ducts 23 and 26, a very rapid exchange of heat will take place between the air flowing through the air ducts and the water passing through the water ducts so that said air will be rapidlycooled. and in such condition will discharge into the room or building that is serviced by, the appag ratus.

The water after absorbing heat from the air circulating through the air ducts will discharge through drip pan I I onto the. cooling, rack within the housing It! and such water will in turn be cooled by the air that is driven by the fan through duct l4 and through the chamber in which said cooling rack is located, 7 A

It is to be understood that the cores of my improved radiator are separately formed and when in superimposed arrangement as illustrated in Fig. 2, said cores rest one upon the other, but are in no wise attached to each other, thus greatly facilitating the manufacture, assembly, disassembly and cleaning of the entire core structure.

Among the particular advantages Y of my improved air-conditioning. radiator are the accomplishment of heat exchange between the air and water within confined limits, economy of manufacture and the feature of ready assembly and taking apart, which enables the complete structure to be easily and conveniently cleaned.

Thus it will be seen that I have provided an air-conditioning radiator that is relatively simple in construction, inexpensive of maunfacture and and very effective in performing the functions for which it is intended.

It will be understood that minor changes in the size, form and construction-of the: various parts of my improved air-conditioning apparatus radiator, may be made and substituted for those herein shown and described, without departing from the spirit of my invention, the scope of which is set forth in the appended claims. 1
